Description

本願発明は、複数の半導体発光素子からの光をリフレクタによって灯具前方へ反射させるように構成された車両用灯具に関するものである。   The present invention relates to a vehicular lamp configured to reflect light from a plurality of semiconductor light emitting elements to the front of the lamp by a reflector.

従来より、例えば「特許文献１」に記載されているように、複数の半導体発光素子からの光をリフレクタによって灯具前方へ反射させるように構成された車両用灯具が知られている。   2. Description of the Related Art Conventionally, as described in, for example, “Patent Document 1”, a vehicular lamp configured to reflect light from a plurality of semiconductor light emitting elements to the front of a lamp with a reflector is known.

また「特許文献２」には、水平方向に直線状に配列された複数の半導体発光素子からの光を、リフレクタによって灯具前方へ反射させるように構成された車両用灯具が記載されている。   Further, “Patent Document 2” describes a vehicular lamp configured to reflect light from a plurality of semiconductor light emitting elements arranged linearly in a horizontal direction to the front of the lamp by a reflector.

特開平１１−３０６８１０号公報Japanese Patent Laid-Open No. 11-306810 特開２００３−３１００７号公報JP 2003-31007 A

上記「特許文献２」に記載された車両用灯具を採用することにより、コンパクトな灯具構成により横長の配光パターンを形成することが可能となるが、灯具正面方向に対して左右方向に大きく傾斜した方向への光照射を十分に行うことができない、という問題がある。   By adopting the vehicular lamp described in the above-mentioned “Patent Document 2”, it becomes possible to form a horizontally long light distribution pattern with a compact lamp configuration, but it is greatly inclined in the left-right direction with respect to the front direction of the lamp. There is a problem that light irradiation in the direction cannot be performed sufficiently.

本願発明は、このような事情に鑑みてなされたものであって、複数の半導体発光素子からの光をリフレクタによって灯具前方へ反射させるように構成された車両用灯具において、灯具正面方向に対して左右方向に大きく傾斜した方向への光照射を十分に行うことができる車両用灯具を提供することを目的とするものである。   The present invention has been made in view of such circumstances, and in a vehicular lamp configured to reflect light from a plurality of semiconductor light-emitting elements toward the front of the lamp by a reflector, An object of the present invention is to provide a vehicular lamp that can sufficiently irradiate light in a direction greatly inclined in the left-right direction.

本願発明は、半導体発光素子からの出射光の向きに工夫を施すことにより、上記目的達成を図るようにしたものである。   The present invention is intended to achieve the above-mentioned object by devising the direction of the emitted light from the semiconductor light emitting device.

すなわち、本願発明に係る車両用灯具は、
複数の半導体発光素子からの光をリフレクタによって灯具前方へ反射させるように構成された車両用灯具において、
上記リフレクタの反射面が、水平方向に延びる焦線を有する放物柱状曲面で構成されており、
上記複数の半導体発光素子が、上記焦線上に所定間隔をおいて配置されるとともに、これら半導体発光素子のうち少なくとも１つの半導体発光素子からの出射光の向きが、上記焦線方向に関して他の半導体発光素子とは異なる向きに設定されている、ことを特徴とするものである。 That is, the vehicular lamp according to the present invention is:
In a vehicular lamp configured to reflect light from a plurality of semiconductor light emitting elements to the front of the lamp by a reflector,
The reflecting surface of the reflector is composed of a parabolic curved surface having a focal line extending in the horizontal direction,
The plurality of semiconductor light emitting elements are arranged at a predetermined interval on the focal line, and the direction of emitted light from at least one semiconductor light emitting element among these semiconductor light emitting elements is different from that of the focal line direction with respect to another semiconductor. It is characterized by being set in a different direction from the light emitting element.

上記「車両用灯具」の種類は特に限定されるものではなく、例えば、ヘッドランプ、フォグランプ、コーナリングランプ、テールランプ、ストップランプ、バックアップランプ、ターンシグナルランプ、デイタイムランニングランプ等が採用可能である。   The type of the “vehicle lamp” is not particularly limited. For example, a head lamp, a fog lamp, a cornering lamp, a tail lamp, a stop lamp, a backup lamp, a turn signal lamp, a daytime running lamp, and the like can be employed.

上記「灯具前方」は、車両前方と一致していてもよいし、一致していなくてもよい。   The “front of the lamp” may or may not coincide with the front of the vehicle.

上記「半導体発光素子」の種類は特に限定されるものではなく、例えば、発光ダイオードやレーザダイオード等が採用可能である。   The type of the “semiconductor light emitting element” is not particularly limited, and for example, a light emitting diode or a laser diode can be employed.

上記構成に示すように、本願発明に係る車両用灯具は、複数の半導体発光素子からの光をリフレクタによって灯具前方へ反射させるように構成されているが、その際、リフレクタの反射面は水平方向に延びる焦線を有する放物柱状曲面で構成されており、また、複数の半導体発光素子はその焦線上に所定間隔をおいて配置されるとともに、これら半導体発光素子のうち少なくとも１つの半導体発光素子からの出射光の向きが、焦線方向に関して他の半導体発光素子とは異なる向きに設定されているので、次のような作用効果を得ることができる。   As shown in the above configuration, the vehicular lamp according to the present invention is configured to reflect light from a plurality of semiconductor light emitting elements to the front of the lamp by the reflector, and in this case, the reflecting surface of the reflector is in the horizontal direction. And a plurality of semiconductor light emitting elements are disposed on the focal line at a predetermined interval, and at least one semiconductor light emitting element among these semiconductor light emitting elements is formed. Since the direction of the emitted light from is set to a direction different from that of other semiconductor light emitting elements with respect to the direction of the focal line, the following effects can be obtained.

すなわち、各半導体発光素子はリフレクタの反射面を構成する放物柱状曲面の焦線上に配置されているので、リフレクタで反射した各半導体発光素子からの光は、上下方向には拡散せずに水平方向にのみ拡散し、これにより灯具前方には横長配光パターンが形成されることとなるが、少なくとも１つの半導体発光素子からの出射光の向きが焦線方向に関して他の半導体発光素子とは異なる向きに設定されているので、複数の横長配光パターンが水平方向にずれた位置に形成されるようにすることができる。   That is, since each semiconductor light emitting element is arranged on the focal line of a parabolic columnar curved surface that constitutes the reflecting surface of the reflector, the light from each semiconductor light emitting element reflected by the reflector is not diffused in the vertical direction but is horizontally diffused. Diffuse only in the direction, thereby forming a horizontally long light distribution pattern in front of the lamp, but the direction of light emitted from at least one semiconductor light emitting element is different from other semiconductor light emitting elements with respect to the focal direction. Since the orientation is set, the plurality of horizontally long light distribution patterns can be formed at positions shifted in the horizontal direction.

したがって本願発明によれば、複数の半導体発光素子からの光をリフレクタによって灯具前方へ反射させるように構成された車両用灯具において、灯具正面方向に対して左右方向に大きく傾斜した方向への光照射を十分に行うことができる。そしてこれにより車両用灯具をコーナリングランプ等に適したものとすることができる。   Therefore, according to the present invention, in a vehicular lamp configured to reflect light from a plurality of semiconductor light emitting elements to the front of the lamp by a reflector, light irradiation in a direction greatly inclined in the left-right direction with respect to the front direction of the lamp Can be done sufficiently. Thus, the vehicular lamp can be made suitable for a cornering lamp or the like.

上記構成において、少なくとも１つの半導体発光素子からの出射光の向きを、焦線方向に関して他の半導体発光素子とは異なる向きに設定するための具体的な構成は特に限定されるものではないが、各半導体発光素子を発光チップとこれを封止する封止樹脂とを備えてなる構成とし、上記少なくとも１つの半導体発光素子と上記他の半導体発光素子とで封止樹脂の封止形状を異なった形状に設定するようにすれば、各半導体発光素子を同一姿勢で配置した状態で、これら半導体発光素子のうち少なくとも１つの半導体発光素子からの出射光の向きを他の半導体発光素子とは異なる向きに設定することができるので、灯具構造を簡素化することができる。   In the above configuration, the specific configuration for setting the direction of emitted light from at least one semiconductor light emitting element to a direction different from other semiconductor light emitting elements with respect to the focal line direction is not particularly limited, Each semiconductor light emitting element is configured to include a light emitting chip and a sealing resin for sealing the light emitting chip, and the sealing shape of the sealing resin is different between the at least one semiconductor light emitting element and the other semiconductor light emitting elements. If the shape is set, the direction of light emitted from at least one of the semiconductor light emitting elements is different from the direction of the other semiconductor light emitting elements in a state where the semiconductor light emitting elements are arranged in the same posture. Therefore, the lamp structure can be simplified.

ここで「封止形状」とは、封止対象となる半導体発光素子を基準位置としたときの封止樹脂の表面形状を意味するものである。そして「封止形状を異なった形状に設定する」ための具体的態様としては、封止樹脂の表面形状自体を異なったものとする態様、封止樹脂の表面形状自体は同一であるがその形成位置を異なったものとする態様、封止樹脂の表面形状およびその形成位置を異なったものとする態様のいずれであってもよい。   Here, the “sealing shape” means the surface shape of the sealing resin when the semiconductor light emitting element to be sealed is used as a reference position. And as a specific mode for “setting the sealing shape to a different shape”, a mode in which the surface shape of the sealing resin itself is different, and the surface shape of the sealing resin itself is the same, but its formation Any of the aspect which makes a position different, the aspect which makes the surface shape of the sealing resin, and its formation position different may be sufficient.

また上記構成において、各半導体発光素子からの出射光の向きを、焦線方向一端部に位置する半導体発光素子から焦線方向他端部に位置する半導体発光素子にかけて徐々に変化するように設定すれば、灯具正面方向から該灯具正面方向に対して左右方向に大きく傾斜した方向まで、複数の横長配光パターンを水平方向に少しずつずらして形成することができ、これにより必要とする向きへの光照射を的確に行うことができる。   In the above configuration, the direction of the emitted light from each semiconductor light emitting element is set so as to gradually change from the semiconductor light emitting element located at one end portion in the focal line direction to the semiconductor light emitting element located at the other end portion in the focal line direction. For example, it is possible to form a plurality of horizontally long light distribution patterns by slightly shifting in the horizontal direction from the lamp front direction to the direction greatly inclined in the left-right direction with respect to the lamp front direction. Light irradiation can be performed accurately.

その際、焦線方向一端部に位置する半導体発光素子からの出射光の向きを焦線方向と略直交する向きに設定するとともに、焦線方向他端部に位置する半導体発光素子からの出射光の向きを焦線方向一端部寄りの向きに設定するようにすれば、各半導体発光素子からの出射光がリフレクタの反射面に入射する位置をかなりの範囲にわたって重複させることができるので、リフレクタの必要幅を小さく抑えることができ、その分だけ車両用灯具をコンパクトに構成することができる。   At that time, the direction of the emitted light from the semiconductor light emitting element located at one end of the focal line direction is set to a direction substantially orthogonal to the focal line direction, and the emitted light from the semiconductor light emitting element located at the other end of the focal line direction Is set to be closer to one end of the focal line direction, the position where the emitted light from each semiconductor light emitting element is incident on the reflecting surface of the reflector can be overlapped over a considerable range. The required width can be kept small, and the vehicular lamp can be configured compactly by that amount.

上記構成において、複数の半導体発光素子は、同時に点灯させるようにしてもよいし、一部の半導体発光素子のみを選択的に点灯させるようにしてもよい。後者の構成を採用した場合には、消費電力を抑えた上で車両走行状況等に応じて必要な方向への光照射を行うことができる。   In the above configuration, the plurality of semiconductor light emitting elements may be turned on simultaneously, or only some of the semiconductor light emitting elements may be selectively turned on. In the case of adopting the latter configuration, it is possible to perform light irradiation in a necessary direction according to a vehicle running condition or the like while suppressing power consumption.

以下、図面を用いて、本願発明の実施の形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅは、白色で発光する発光ダイオードであって、発光チップ２２ａと、この発光チップ２２ａを略半球状に覆うようにして封止する封止樹脂２２ｂとを備えてなっている。これら各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅは、焦線ＦＬ上に所定間隔をおいて配置されており、その発光チップ２２ａを上方へ向けた状態で、各々基板２６を介して支持部材２８に固定されている。   Each of the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E is a light emitting diode that emits white light, and includes a light emitting chip 22a and a sealing resin 22b that seals the light emitting chip 22a so as to cover the light emitting chip 22a. It is equipped with. Each of these semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E is arranged at a predetermined interval on the focal line FL, and is supported via the substrate 26 with the light emitting chip 22a facing upward. It is fixed to the member 28.

その際、各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅの出射光の向きは、焦線ＦＬを含む鉛直面内において、焦線ＦＬ方向に関して互いに異なる向きに設定されている。具体的には、車幅方向内側端部に位置する半導体発光素子２２Ａからの出射光の向きは、鉛直上方に設定されており、その隣りに位置する半導体発光素子２２Ｂからの出射光の向きは、鉛直上方に対して車幅方向外側に１０°程度傾斜した向きに設定されており、その隣りに位置する半導体発光素子２２Ｃからの出射光の向きは、鉛直上方に対して車幅方向外側に２０°程度傾斜した向きに設定されており、その隣りに位置する半導体発光素子２２Ｄからの出射光の向きは、鉛直上方に対して車幅方向外側に３０°程度傾斜した向きに設定されており、車幅方向外側端部に位置する半導体発光素子２２Ｆからの出射光の向きは、鉛直上方に対して車幅方向外側に４０°程度傾斜した向きに設定されている。   At this time, the directions of the emitted light from the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E are set to be different from each other with respect to the direction of the focal line FL in the vertical plane including the focal line FL. Specifically, the direction of the emitted light from the semiconductor light emitting element 22A located at the inner end in the vehicle width direction is set vertically upward, and the direction of the emitted light from the semiconductor light emitting element 22B located adjacent thereto is The direction of the emitted light from the semiconductor light emitting element 22C located adjacent to the upper side in the vehicle width direction is set to the outer side in the vehicle width direction with respect to the upper vertical direction. The direction of light emitted from the adjacent semiconductor light emitting element 22D is set to a direction inclined about 30 ° outward in the vehicle width direction with respect to the vertical direction. The direction of the emitted light from the semiconductor light emitting element 22F located at the outer end portion in the vehicle width direction is set to be inclined by about 40 ° outward in the vehicle width direction with respect to the vertically upward direction.

これを実現するため、支持部材２８は、半導体発光素子２２Ａ以外の４つの半導体発光素子２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅの基板２６を支持する部分が、互いに異なる傾斜角を有する斜面状に形成されている。   In order to realize this, the support member 28 is formed such that the portions of the four semiconductor light emitting elements 22B, 22C, 22D, and 22E other than the semiconductor light emitting element 22A that support the substrate 26 have inclined surfaces having different inclination angles. Yes.

図３に示すように、リフレクタ２４の反射面２４ａは、その焦線ＦＬと直交する鉛直断面の形状が灯具前後方向に延びる軸線Ａｘを軸とする放物線で構成されており、また、各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅは焦線ＦＬ上に配置されているので、リフレクタ２４で反射した各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅからの光は、上下方向には拡散せずに水平方向にのみ拡散し、これにより灯具前方には横長配光パターンが形成されることとなる。   As shown in FIG. 3, the reflecting surface 24a of the reflector 24 is configured by a parabola whose axis is perpendicular to the focal line FL and whose axis is an axis Ax extending in the front-rear direction of the lamp. Since the elements 22A, 22B, 22C, 22D, and 22E are disposed on the focal line FL, the light from each of the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E reflected by the reflector 24 is diffused in the vertical direction. Without spreading, only the horizontal direction is diffused, whereby a horizontally long light distribution pattern is formed in front of the lamp.

図４は、各半導体発光素子２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅを１つずつ点灯させたときに、リフレクタ２４からの反射光により車両前方２５ｍの位置に配置された仮想鉛直スクリーン上に形成される横長配光パターンＰａ、Ｐｂ、Ｐｃ、Ｐｄ、Ｐｅを示す図である。   FIG. 4 shows a horizontally long shape formed on a virtual vertical screen disposed at a position 25 m ahead of the vehicle by reflected light from the reflector 24 when each of the semiconductor light emitting elements 22B, 22C, 22D, and 22E is turned on one by one. It is a figure which shows the light distribution pattern Pa, Pb, Pc, Pd, and Pe.

同図（ａ）に示すように、鉛直上方へ向けて配置された半導体発光素子２２Ａを点灯させたときに形成される横長配光パターンＰａは。灯具正面方向（すなわち車両正面方向から左側に所定角度θ傾斜した方向）を中心として水平方向に広がる配光パターンとなる。   As shown in FIG. 5A, a horizontally long light distribution pattern Pa formed when the semiconductor light emitting element 22A arranged vertically upward is turned on. The light distribution pattern spreads in the horizontal direction around the lamp front direction (that is, the direction inclined at a predetermined angle θ to the left from the vehicle front direction).

また、同図（ｂ）〜（ｅ）に示すように、鉛直上方から傾斜した向きに配置された半導体発光素子２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅを点灯させたときに形成される横長配光パターンＰｂ、Ｐｃ、Ｐｄ、Ｐｅは。横長配光パターンＰａよりもさらに左側において水平方向に広がる配光パターンとなる。その際、各横長配光パターンＰｂ、Ｐｃ、Ｐｄ、Ｐｅの横長配光パターンＰａからの左方向変位量は、各半導体発光素子２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅの傾斜角度に略比例した値となっている。   Further, as shown in FIGS. 7B to 7E, the horizontally long light distribution pattern Pb formed when the semiconductor light emitting elements 22B, 22C, 22D, and 22E arranged in the direction inclined from the vertical upper side are turned on. , Pc, Pd, Pe. The light distribution pattern spreads in the horizontal direction on the left side of the horizontally long light distribution pattern Pa. At that time, the leftward displacement amount of each of the horizontally long light distribution patterns Pb, Pc, Pd, and Pe from the horizontally long light distribution pattern Pa is a value that is substantially proportional to the inclination angle of each of the semiconductor light emitting elements 22B, 22C, 22D, and 22E. ing.

同図において、２点鎖線で示す配光パターンＰＬは、図示しないヘッドランプからの光照射によって形成されるロービーム用配光パターンである。このロービーム用配光パターンＰＬは、上端部に水平カットオフラインＣＬ１および斜めカットオフラインＣＬ２を有しており、両カットオフラインの交点であるエルボ点Ｅは、車両正面方向の消点であるＨ−Ｖのやや下方（具体的には０．５〜０．６°程度下方）に位置している。そして、このロービーム用配光パターンＰＬには、エルボ点Ｅをやや左寄りに囲むようにしてホットゾーンＨＺが形成されている。   In the figure, a light distribution pattern PL indicated by a two-dot chain line is a low beam light distribution pattern formed by light irradiation from a headlamp (not shown). The light distribution pattern for low beam PL has a horizontal cut-off line CL1 and an oblique cut-off line CL2 at the upper end, and an elbow point E that is the intersection of both cut-off lines is a vanishing point in the vehicle front direction HV It is located slightly below (specifically, about 0.5 to 0.6 ° below). In the low beam light distribution pattern PL, a hot zone HZ is formed so as to surround the elbow point E slightly to the left.

本実施形態に係る車両用灯具１０においては、各横長配光パターンＰａ、Ｐｂ、Ｐｃ、Ｐｄ、Ｐｅの上端縁が水平カットオフラインＣＬ１よりも僅かに下方に位置するよう、灯具ユニット１６は灯室内においてやや下向きに（すなわち軸線Ａｘが灯具前後方向に対してやや下向きに）なるようにして配置されている。   In the vehicular lamp 10 according to the present embodiment, the lamp unit 16 is installed in the lamp chamber so that the upper edge of each horizontally long light distribution pattern Pa, Pb, Pc, Pd, Pe is positioned slightly below the horizontal cut-off line CL1. Are arranged so as to be slightly downward (that is, the axis Ax is slightly downward with respect to the longitudinal direction of the lamp).

本実施形態に係る車両用灯具１０は、ヘッドランプが点灯している状態において、車両を左方向へ旋回させるステアリング操作が行われたとき、あるいは左折方向のウインカ操作が行われたときに、旋回方向前方を照射するようになっている。その際、５つの半導体発光素子２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅのうち所定の３つの半導体発光素子が選択的に点灯するようになっている。   The vehicular lamp 10 according to the present embodiment turns when a steering operation for turning the vehicle to the left or a turn signal operation in the left turn direction is performed in a state where the headlamp is lit. Irradiate in the front direction. At that time, predetermined three semiconductor light emitting elements among the five semiconductor light emitting elements 22B, 22C, 22D, and 22E are selectively lit.

図５は、左折方向のウインカ操作が行われたときに、車両用灯具１０からの照射光により上記仮想鉛直スクリーン上に形成される配光パターンを透視的に示す図である。   FIG. 5 is a perspective view showing a light distribution pattern formed on the virtual vertical screen by the irradiation light from the vehicular lamp 10 when the turn signal operation in the left turn direction is performed.

同図に示すように、左折方向のウインカ操作が行われたときには、まだステアリング操作が行われていなくても、３つの半導体発光素子２２Ａ、２２Ｂ、２２Ｃが点灯して、３つの横長配光パターンＰａ、Ｐｂ、Ｐｃからなる合成横長配光パターンＰ１を形成するようになっている。そしてこれにより、ロービーム用配光パターンＰＬと共に車両左前方路面を明るく照射し、左折進入路に対する視認性を高めるようになっている。   As shown in the figure, when the turn signal operation in the left turn direction is performed, the three semiconductor light emitting elements 22A, 22B, and 22C are lit up and the three horizontally long light distribution patterns even if the steering operation is not yet performed. A combined horizontally long light distribution pattern P1 made of Pa, Pb, and Pc is formed. Thereby, the vehicle left front road surface is illuminated brightly together with the low beam light distribution pattern PL, so that the visibility to the left turn approach road is enhanced.

図６は、実際にステアリング操作が行われたときに、車両用灯具１０からの照射光により上記仮想鉛直スクリーン上に形成される配光パターンを示す図である。   FIG. 6 is a diagram showing a light distribution pattern formed on the virtual vertical screen by the irradiation light from the vehicular lamp 10 when the steering operation is actually performed.

同図（ａ）に示すように、ステアリング舵角が小さいときには、ウインカ操作が行われたときと同様、３つの半導体発光素子２２Ａ、２２Ｂ、２２Ｃが点灯して、３つの横長配光パターンＰａ、Ｐｂ、Ｐｃからなる合成横長配光パターンＰ１を形成し、ロービーム用配光パターンＰＬと共に車両左前方路面を明るく照射するようになっている。   As shown in FIG. 5A, when the steering angle is small, the three semiconductor light emitting elements 22A, 22B, and 22C are turned on, and the three horizontally long light distribution patterns Pa, as when the winker operation is performed. A combined horizontally long light distribution pattern P1 composed of Pb and Pc is formed, and the vehicle left front road surface is illuminated brightly together with the low beam light distribution pattern PL.

同図（ｂ）に示すように、ステアリング舵角がある程度大きくなったときには、３つの半導体発光素子２２Ｂ、２２Ｃ、２２Ｄが点灯して、３つの横長配光パターンＰｂ、Ｐｃ、Ｐｄからなる合成横長配光パターンＰ２を形成し、これにより車両正面方向に対して左側に大きく傾斜した方向への光照射を十分に行うようになっている。   As shown in FIG. 4B, when the steering angle is increased to some extent, the three semiconductor light emitting elements 22B, 22C, and 22D are turned on, and the combined horizontal long pattern composed of the three horizontal light distribution patterns Pb, Pc, and Pd. A light distribution pattern P2 is formed so that light is sufficiently irradiated in a direction greatly inclined to the left with respect to the vehicle front direction.

同図（ｃ）に示すように、ステアリング舵角がさらに大きくなったときには、３つの半導体発光素子２２Ｃ、２２Ｄ、２２Ｅが点灯して、３つの横長配光パターンＰｃ、Ｐｄ、Ｐｅからなる合成横長配光パターンＰ３を形成し、これにより車両正面方向に対して左側にさらに大きく傾斜した方向への光照射を十分に行うようになっている。   As shown in FIG. 6C, when the steering angle is further increased, the three semiconductor light emitting elements 22C, 22D, and 22E are turned on, and the combined horizontal long pattern composed of the three horizontal light distribution patterns Pc, Pd, and Pe. A light distribution pattern P3 is formed so that light is sufficiently irradiated in a direction further inclined to the left with respect to the vehicle front direction.

以上詳述したように、本実施形態に係る車両用灯具１０は、５つの半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅからの光をリフレクタ２４によって灯具前方へ反射させるように構成されているが、その際、リフレクタ２４の反射面２４ａは水平方向に延びる焦線ＦＬを有する放物柱状曲面で構成されており、また、これら半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅは焦線ＦＬ上に所定間隔をおいて配置されるとともに、その出射光の向きが焦線ＦＬ方向に関して各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅ毎に異なる向きに設定されているので、次のような作用効果を得ることができる。   As described above in detail, the vehicular lamp 10 according to this embodiment is configured to reflect the light from the five semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E to the front of the lamp by the reflector 24. However, in this case, the reflecting surface 24a of the reflector 24 is configured by a parabolic columnar curved surface having a focal line FL extending in the horizontal direction, and these semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E have a focal line FL. Since the direction of the emitted light is set differently for each of the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E with respect to the direction of the focal line FL, Advantageous effects can be obtained.

すなわち、各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅは、リフレクタ２４の反射面２４ａを構成する放物柱状曲面の焦線ＦＬ上に配置されているので、リフレクタ２４で反射した各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅからの光は、上下方向には拡散せずに水平方向にのみ拡散し、これにより灯具前方には横長配光パターンＰａ、Ｐｂ、Ｐｃ、Ｐｄ、Ｐｅが形成されることとなるが、各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅからの出射光の向きは焦線ＦＬ方向に関して各々異なる向きに設定されているので、５つの横長配光パターンＰａ、Ｐｂ、Ｐｃ、Ｐｄ、Ｐｅを互いに水平方向にずれた位置に形成することができる。   That is, each of the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E is disposed on the focal line FL of the parabolic curved surface constituting the reflecting surface 24a of the reflector 24. The light from the elements 22A, 22B, 22C, 22D, and 22E is not diffused in the vertical direction but is diffused only in the horizontal direction, whereby the horizontally long light distribution patterns Pa, Pb, Pc, Pd, and Pe are formed in front of the lamp. Although formed, the directions of the emitted light from the respective semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E are set in different directions with respect to the focal line FL direction. , Pb, Pc, Pd, and Pe can be formed at positions shifted in the horizontal direction.

したがって本実施形態によれば、灯具正面方向に対して左側に大きく傾斜した方向への光照射を十分に行うことができる。そしてこれにより車両用灯具１０をコーナリングランプに適したものとすることができる。   Therefore, according to the present embodiment, it is possible to sufficiently irradiate light in a direction greatly inclined to the left with respect to the front direction of the lamp. Thus, the vehicular lamp 10 can be made suitable for a cornering lamp.

しかも本実施形態においては、各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅからの出射光の向きが、焦線方向一端部に位置する半導体発光素子２２Ａから焦線方向他端部に位置する半導体発光素子２２Ｅにかけて徐々に変化するように設定されているので、灯具正面方向から該灯具正面方向に対して左右方向に大きく傾斜した方向まで、５つの横長配光パターンＰａ、Ｐｂ、Ｐｃ、Ｐｄ、Ｐｅを水平方向に少しずつずらして形成することができ、これにより必要とする向きへの光照射を的確に行うことができる。   Moreover, in the present embodiment, the direction of the emitted light from each of the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E is located at the other end in the focal line direction from the semiconductor light emitting element 22A located at one end in the focal line direction. Since it is set so as to gradually change over the semiconductor light emitting element 22E, five horizontally long light distribution patterns Pa, Pb, Pc, Pd from the lamp front direction to the direction greatly inclined in the left-right direction with respect to the lamp front direction. , Pe can be formed while being shifted little by little in the horizontal direction, so that light irradiation in a required direction can be performed accurately.

また本実施形態においては、５つの半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅのうち３つの半導体発光素子のみが選択的に点灯するようになっているので、消費電力を抑えた上で車両走行状況等に応じて必要な方向への光照射を行うことができる。   In the present embodiment, only three semiconductor light emitting elements among the five semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E are selectively turned on. Light irradiation in a necessary direction can be performed in accordance with traveling conditions and the like.

さらに本実施形態に係る車両用灯具１０は、その正面方向が車両正面方向に対して左側に所定角度θ傾斜した方向に設定されているので、灯具正面方向に対して左側に大きく傾斜した方向への光照射を一層容易に行うことができる。   Furthermore, since the front direction of the vehicular lamp 10 according to the present embodiment is set in a direction that is inclined to the left by a predetermined angle θ with respect to the front direction of the vehicle, the direction is greatly inclined to the left with respect to the front direction of the lamp. The light irradiation can be performed more easily.

なお、上記実施形態においては、その車両用灯具１０が車両左前端部に配置されるコーナリングランプである場合について説明したが、車両右前端部に配置されるコーナリングランプである場合にも、上記車両用灯具１０と左右対称の構成とすれば、上記実施形態と同様の作用効果を得ることができる。   In the above embodiment, the case where the vehicle lamp 10 is a cornering lamp disposed at the left front end of the vehicle has been described. However, the above vehicle can also be used when the vehicle lamp 10 is a cornering lamp disposed at the right front end of the vehicle. If the configuration is symmetrical to the lamp 10, it is possible to obtain the same effects as the above embodiment.

また、上記実施形態においては、車両用灯具１０が、ランプボディ１２と透光カバー１４とで形成される灯室内に灯具ユニット１６が収容されてなる構成である場合について説明したが、灯具ユニット１６に透光カバー等を直接取り付けて車両用灯具を構成することも可能であり、このようにした場合においても、上記実施形態と同様の作用効果を得ることができる。   Further, in the above embodiment, the case where the vehicular lamp 10 has a configuration in which the lamp unit 16 is housed in the lamp chamber formed by the lamp body 12 and the translucent cover 14 has been described. It is also possible to construct a vehicular lamp by directly attaching a translucent cover or the like to this, and even in this case, the same effect as the above embodiment can be obtained.

次に上記実施形態の変形例について説明する。   Next, a modification of the above embodiment will be described.

図７は、上記実施形態の第１変形例に係る車両用灯具を示す、図１と同様の図であり、図８は、その灯具ユニットを示す、図２と同様の図である。   FIG. 7 is a view similar to FIG. 1 showing a vehicular lamp according to a first modification of the above embodiment, and FIG. 8 is a view similar to FIG. 2 showing the lamp unit.

これらの図に示すように、本変形例に係る車両用灯具１１０においても、その灯具ユニット１１６が、５つの半導体発光素子１２２Ａ、１２２Ｂ、１２２Ｃ、１２２Ｄ、１２２Ｅからの光をリフレクタ１２４によって灯具前方へ反射させるように構成されるとともに、各半導体発光素子１２２Ａ、１２２Ｂ、１２２Ｃ、１２２Ｄ、１２２Ｅが、リフレクタ１２４の反射面１２４ａを構成する放物柱状曲面の焦線ＦＬ上に所定間隔をおいて配置されている点は、上記実施形態の場合と同様であるが、各半導体発光素子１２２Ａ、１２２Ｂ、１２２Ｃ、１２２Ｄ、１２２Ｅの配列が上記実施形態とは異なっている。   As shown in these drawings, also in the vehicular lamp 110 according to this modification, the lamp unit 116 uses the reflector 124 to transmit the light from the five semiconductor light emitting elements 122A, 122B, 122C, 122D, and 122E to the front of the lamp. Each of the semiconductor light emitting elements 122A, 122B, 122C, 122D, and 122E is configured to be reflected, and is disposed at a predetermined interval on the focal line FL of the parabolic curved surface that constitutes the reflecting surface 124a of the reflector 124. However, the arrangement of the semiconductor light emitting elements 122A, 122B, 122C, 122D, and 122E is different from that of the above embodiment.

すなわち、これら各半導体発光素子１２２Ａ、１２２Ｂ、１２２Ｃ、１２２Ｄ、１２２Ｅの支持部材１２８への取付姿勢は、上記実施形態の各半導体発光素子２２Ａ、２２Ｂ、２２Ｃ、２２Ｄ、２２Ｅの取付姿勢と各々対応しているが、その際、上記実施形態とは逆に、半導体発光素子２２Ａに対応する半導体発光素子１２２Ａが車幅方向外側端部に位置しており、半導体発光素子２２Ｅに対応する半導体発光素子１２２Ｅが車幅方向内側端部に位置している。そして、車幅方向外側端部に位置する半導体発光素子１２２Ａからの出射光の向きは、鉛直上方に設定されており、車幅方向内側端部に位置する半導体発光素子１２２Ｅからの出射光の向きは、車幅方向外側端部寄りに大きく傾斜した向きに設定されており、その中間に位置する半導体発光素子１２２Ｂ、１２２Ｃ、１２２Ｄからの出射光の向きは、この順で車幅方向外側端部寄りに徐々に大きく傾斜した向きに設定されている。   That is, the mounting posture of each of the semiconductor light emitting elements 122A, 122B, 122C, 122D, and 122E to the support member 128 corresponds to the mounting posture of each of the semiconductor light emitting elements 22A, 22B, 22C, 22D, and 22E of the above embodiment. However, in this case, contrary to the above embodiment, the semiconductor light emitting element 122A corresponding to the semiconductor light emitting element 22A is located at the outer end in the vehicle width direction, and the semiconductor light emitting element 122E corresponding to the semiconductor light emitting element 22E. Is located at the inner end in the vehicle width direction. The direction of the emitted light from the semiconductor light emitting element 122A located at the outer end in the vehicle width direction is set vertically upward, and the direction of the emitted light from the semiconductor light emitting element 122E located at the inner end in the vehicle width direction Is set in a direction that is largely inclined toward the outer end in the vehicle width direction, and the direction of the emitted light from the semiconductor light emitting elements 122B, 122C, 122D located in the middle thereof is the outer end in the vehicle width direction in this order. The direction is set to be gradually inclined toward the side.

本変形例の構成を採用することにより、各半導体発光素子１２２Ａ、１２２Ｂ、１２２Ｃ、１２２Ｄ、１２２Ｅからの出射光がリフレクタ１２４の反射面１２４ａに入射する位置をかなりの範囲にわたって重複させることができるので、図８に２点鎖線で示す上記実施形態のリフレクタ２４に対して同図に実線で示すように、リフレクタ１２４の必要幅を小さく抑えることができる。そして、その分だけ車両用灯具１１０をコンパクトに構成することができる。   By adopting the configuration of this modification, it is possible to overlap the position where the emitted light from each of the semiconductor light emitting elements 122A, 122B, 122C, 122D, and 122E enters the reflecting surface 124a of the reflector 124 over a considerable range. The required width of the reflector 124 can be kept small as shown by the solid line in FIG. 8 with respect to the reflector 24 of the above embodiment shown by the two-dot chain line in FIG. And the vehicle lamp 110 can be comprised compactly by that much.

図９は、上記実施形態の第２変形例に係る灯具ユニット２１６を示す、図２と同様の図であり、図１０は、図９のＸ部詳細図である。   FIG. 9 is a view similar to FIG. 2 showing a lamp unit 216 according to a second modification of the embodiment, and FIG. 10 is a detailed view of a portion X in FIG.

図９に示すように、本変形例に係る灯具ユニット２１６も、５つの半導体発光素子２２２Ａ、２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅからの光をリフレクタ２２４によって灯具前方へ反射させるように構成されるとともに、各半導体発光素子２２２Ａ、２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅが、リフレクタ２２４の反射面２２４ａを構成する放物柱状曲面の焦線ＦＬ上に所定間隔をおいて配置されている点は、上記実施形態の場合と同様であるが、各半導体発光素子２２２Ａ、２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅ自体の構成およびその支持部材２２８への取付姿勢が上記実施形態とは異なっている。   As shown in FIG. 9, the lamp unit 216 according to this modification is also configured to reflect light from the five semiconductor light emitting elements 222A, 222B, 222C, 222D, and 222E to the front of the lamp by the reflector 224, and Each semiconductor light emitting element 222A, 222B, 222C, 222D, 222E is arranged at a predetermined interval on the focal line FL of the parabolic columnar curved surface constituting the reflecting surface 224a of the reflector 224. Although the same as the case, the configuration of each semiconductor light emitting element 222A, 222B, 222C, 222D, 222E itself and its mounting posture to the support member 228 are different from the above embodiment.

すなわち、これら各半導体発光素子２２２Ａ、２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅは、いずれも上記実施形態の半導体発光素子２２Ａのように鉛直上方へ向けて配置されており、その封止樹脂の封止形状は互いに異なった形状に設定されている。   That is, each of these semiconductor light emitting elements 222A, 222B, 222C, 222D, and 222E is arranged vertically upward like the semiconductor light emitting element 22A of the above embodiment, and the sealing shape of the sealing resin is Different shapes are set.

具体的には、車幅方向外側端部に位置する半導体発光素子２２２Ａの封止樹脂２２２Ａｂは、その発光チップ２２２Ａａを中心とする略半球状の表面形状を有しているが、それ以外の半導体発光素子２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅの封止樹脂２２２Ｂｂ、２２２Ｃｂ、２２２Ｄｂ、２２２Ｅｂは、その封止対象となる発光チップ２２２Ｂａ、２２２Ｃａ、２２２Ｄａ、２２２Ｅａよりも車幅方向外側端部寄りの位置を中心とする略半球状の表面形状を有しており、その変位量は、半導体発光素子２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅの順で徐々に大きくなるように設定されている。   Specifically, the sealing resin 222Ab of the semiconductor light emitting element 222A located at the outer end in the vehicle width direction has a substantially hemispherical surface shape centered on the light emitting chip 222Aa. The sealing resins 222Bb, 222Cb, 222Db, and 222Eb of the light emitting elements 222B, 222C, 222D, and 222E are centered at positions closer to the outer end in the vehicle width direction than the light emitting chips 222Ba, 222Ca, 222Da, and 222Ea to be sealed. The displacement amount is set so as to gradually increase in the order of the semiconductor light emitting elements 222B, 222C, 222D, and 222E.

図１０に半導体発光素子２２２Ｃを例にとって示すように、封止樹脂２２２Ｃｂは発光チップ２２２Ｃａに対して車幅方向外側端部寄りに変位しているので、発光チップ２２２Ｃａからの出射光は封止樹脂２２２Ｃｂの表面に対して垂直には入射せず、したがって該表面において車幅方向外側端部寄りに屈折することとなる。そしてこれにより、半導体発光素子２２２Ｃからの出射光の向きは、鉛直上方に対して車幅方向外側に傾斜した向きとなる。その際、各封止樹脂２２２Ｂｂ、２２２Ｃｂ、２２２Ｄｂ、２２２Ｅｂの変位量を適当に設定することにより、各半導体発光素子２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅの出射光の向きを、上記実施形態の場合と同様、鉛直上方に対して車幅方向外側に１０°、２０°、３０°、４０°程度傾斜した向きに設定することができる。   As shown in FIG. 10 using the semiconductor light emitting element 222C as an example, the sealing resin 222Cb is displaced closer to the outer end in the vehicle width direction with respect to the light emitting chip 222Ca. The light does not enter perpendicularly to the surface of 222Cb, and therefore refracts toward the outer end in the vehicle width direction on the surface. As a result, the direction of the emitted light from the semiconductor light emitting element 222C is inclined outward in the vehicle width direction with respect to the vertically upward direction. At that time, by appropriately setting the displacement amount of each sealing resin 222Bb, 222Cb, 222Db, 222Eb, the direction of the emitted light of each semiconductor light emitting element 222B, 222C, 222D, 222E is the same as in the case of the above embodiment. Further, it can be set in a direction inclined about 10 °, 20 °, 30 °, 40 ° outward in the vehicle width direction with respect to the vertical upper side.

本変形例の構成を採用することにより、各半導体発光素子２２２Ａ、２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅを同一姿勢で配置した状態で、その出射光の向きを各半導体発光素子２２２Ａ、２２２Ｂ、２２２Ｃ、２２２Ｄ、２２２Ｅ毎に異なる向きに設定することができるので、支持部材２２８を平板状に形成することができ、これにより灯具構造を簡素化することができる。   By adopting the configuration of this modification, in the state where the semiconductor light emitting elements 222A, 222B, 222C, 222D, and 222E are arranged in the same posture, the direction of the emitted light is changed to the respective semiconductor light emitting elements 222A, 222B, 222C, and 222D. , 222E can be set in different directions, so that the support member 228 can be formed in a flat plate shape, thereby simplifying the lamp structure.

図１１は、上記実施形態の第３変形例に係る灯具ユニット３１６を示す、図３と同様の図である。   FIG. 11 is a view similar to FIG. 3, showing a lamp unit 316 according to a third modification of the embodiment.

同図に示すように、本変形例に係る灯具ユニット３１６は、その基本的構成は上記実施形態の場合と同様であるが、半導体発光素子３２２Ａの向きが、鉛直上方に対して灯具後方側へ所定角度傾斜した向きに設定されており、支持部材３２８もこれに対応した形状となっている。なお、図示しない残り４つの半導体発光素子の向きについても、この半導体発光素子３２２Ａと同様、鉛直上方に対して灯具後方側へ所定角度傾斜した向きに設定されている。   As shown in the figure, the lamp unit 316 according to this modification has the same basic configuration as that of the above embodiment, but the direction of the semiconductor light emitting element 322A is toward the rear side of the lamp with respect to the vertical upward direction. The direction inclined by a predetermined angle is set, and the support member 328 has a shape corresponding to this. Note that the directions of the remaining four semiconductor light emitting elements (not shown) are set to be inclined at a predetermined angle to the rear side of the lamp with respect to the vertically upward direction, similarly to the semiconductor light emitting element 322A.

本変形例の構成を採用することにより、半導体発光素子３２２Ａからリフレクタ３２４の反射面３２４ａへの入射位置を灯具後方寄りにずらすことができるので、その分だけリフレクタ３２４の前方突出長を短くすることができ、これにより灯具ユニット３１６の小型化を図ることができる。   By adopting the configuration of this modification, the incident position from the semiconductor light emitting element 322A to the reflecting surface 324a of the reflector 324 can be shifted toward the rear of the lamp, and accordingly, the front protrusion length of the reflector 324 is shortened accordingly. Thus, the lamp unit 316 can be reduced in size.
